MECHANISM FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 300,542, dated June Applicution filed May 1, 158-1. (No model.)

To on whom it may concern:

Be it known that I, NORMAN 1). Watts, of Hastings, Dakota county,Minnesota, have in vented a new and Improved Mechanism for ConvertingMotion, of which the following is responding parts in all the figures.

Figure 1. is an elevation of my improved mechanism. Fig. 2 is a detailsection of the wheel, bands, and pawls; and Fig. 3 is a plan view of thesame parts.

The shaft a to be rotated carries awheel, d, which has a grooved ordouble-flanged periphery. b b are arms loose upon the shaft, and forkedto pass'at both sides of the wheel. a c are friction-bands around thewheel d, having their ends turned outward between cross-pins w e on armsI), so that the bands are held in place each by one of the arms. ff arepawls or dogs pivoted by pins at f, between the forked or outer ends ofthe arms I), and having their inner ends recessed, to receive the endsof bands 0., g is a pivoted beam, to which reciprocating motion is to beapplied, and h h are rods pivoted to the beam, and connected at theirouter ends to the pawls on arms I), the arms being at opposite sides ofthe wheel. It will be seen that by this construction and arrangement themovement of beam (1 causes an np-and-down movement of the arms I) withthe dogs and the bands 0, the swing of the dogs being limited by thebands. Now, if the pawls are held from moving on their pivots except inone direction, each will cause one band to clamp when carried in onedirection and not in the other. To hold the pawls, I provide arms i. 'i,loose on shaft a, having pins It at their ends, that project throughslots in arms b into the recessed ends of the pawls and between thebent-out ends of bands 0, and the arms'are connected by links I Z to arod, on, from a spring-lever, a. By moving the lever in the onedirection or the other, the arms 2' are swung and pins it moved inopposite directions, so that the pawls are free to compress the bands,one pawl acting while the other is held. In this manner continuousrotary motion. in one direction is given to wheel (1 and shaft (1..

A flywheel may be used, as shown at 0, to equalize the movement. Thealternate movement may be given to the rods h by a beam, :2. treadle, orby any suitable device, and in cases where motion in one direction onlyis desired the pins in may be fixtures; or equivalent devices may beused to hold the pawls.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination and arrangement, substantially asdescribed, of the operating-rods h, pawls f, arms b, bands 0 0, pins orstops it, wheel (1, and shaft a, for operation to give a continuousrotary motion to the shaft, as specified.

2. The combination of lever n, rod m, links 3 1, arms 11, and pins Itwith the pawl-arms Z1, pawls f, bands 0, and wheel d, substantially asand for the purpose specified.
